A Restek® LC guard cartridge in an EXP® direct connect holder is the ultimate in column protection. To help protect your investment and further extend the life of our already-rugged LC columns, Restek offers the patent-pending guard column hardware developed by Optimize Technologies.Raptor™ EXP® Guard Column Cartridges Features: Free-Turn® architecture lets you change cartridges by hand without breaking inlet/outlet fluid…

The Raptor™ ARC-18 column is made specifically for high-throughput, low–sample prep LC-MS/MS applications. A well-balanced retention profile offers better detection and integration of large, multiclass analyte lists, and steric protection helps this SPP column endure the harsh, low-pH mobile phases needed for mass spec without sacrificing retention or peak quality. Restek chemists became the first to combine the speed of supe…

Diluted and DEA-exempt—no need to purchase costly neat materials or make your own standards. Pair with Restek's THC standards to analyze both neutrals and acids in cannabis products by LC. A must for accurate quantification in medical cannabis potency testing and strain ID. Acetonitrile solvent helps maintain stability by preventing methylation of the carboxylic acid group on the molecule. Certified reference materia…

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. Every LC lab has a cache of C18s, but every C18 is not created equal. Because t…

Force LC columns are available with Restek's most popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.

Force LC columns are available with Restek's most popular and highly selective Biphenyl and FluoroPhenyl phases, as well as a general-purpose C18.

The culmination of 20+ years in LC, Force performance LC columns are long-lasting and reproducible, even under the stress of UHPLC. Premium quality is backed by the strength of our 100% Pure Satisfaction guarantee. And perhaps most important, Force columns are fully scalable between 3 or 5 μm HPLC and 1.8 μm UHPLC, so you can easily transfer and optimize methods without extensive calculations.   Force FluoroPhenyl LC…

Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or "core-shell" particles) with the resolution of highly selective USLC technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times with existing HPLC and UHPLC instrumentation.  Stationary Phase Category: Proprietary Ligand Type: Proprietary Partic…

Gold plating provides enhanced inertness versus stainless steel.

The Ultra line represents Restek’s broadest selection of stationary phases on a single silica support. Made of high-purity, type-B silica that minimizes activity and creates high-density bonding, these columns are designed for selective and reliable HPLC applications.

With Raptor™ LC columns, Restek chemists became the first to combine the speed of superficially porous particles (also known as SPP or “core-shell” particles) with the resolution of highly selective USLC® technology. This new breed of chromatographic column allows you to more easily achieve peak separation and faster analysis times without expensive UHPLC instrumentation. SPP core-shell columns commonly employ traditional phe…

Separate a wide variety of polar analytes with a novel hybrid stationary phase

The EXP® Hand-Tight Nut & Titanium Hybrid Ferrule fitting system is the premier adjustable nut and ferrule compression fitting for extreme high-pressure connections between 1/16" tubing and any 10-32 port. The patent-pending Titanium Hybrid Ferrule integrates the resilience of titanium with the proven sealing ability of PEEK in a superb one-piece design. The Hybrid Ferrule provides a perfect seal with every connection, yet the…

The EXP® Pre-Column Filter is ideal for protecting small-particle UHPLC columns at extreme pressures. Such techniques analyze samples in the most demanding applications, which can decrease the life of these expensive columns. EXP® Pre-Column Filters help extend that life and protect your column investment without sacrificing performance. Free-Turn® architecture allows the user to change cartridges by hand without breaking flui…

OPTI-GUARD® 1mm Guard Columns set the standard for extremely low impact, easy to use pre-column protection. Designed for use with analytical (4.6, 3.0 mm i.d.) and narrow-bore (2.1, 1.0 mm i.d.) columns, the patented floating stem design automatically adjusts to any manufacturer's tube stop depth for a zero-dead-volume connection every time. The best part? It's no larger than a standard fitting. Connecting the OPTI-GUARD® requ…

The OPTI-PAK Trap Columns unique hardware design integrates a PEEK holder with an auto-adjusting stem which provides a fluid interface with any 10-32 standard injector port, and guarantees a zero-dead-volume connection despite variances in tube stop depth. A proprietary method of frit placement allows the packed stem to be positioned directly into the flow path, which eliminates all excess swept volume. Less swept volume trans…

Optimize Technologies, precision machine their components to the most exacting standards in the industry. Everything in the manufacturing process is controlled to ensure the continuing quality that has long been associated with the Optimize name. From the individual matching of check valve ball and seat sets to the proprietary blend of materials in our seals - experience the Optimize advantage.Most instrument manufacturers wil…

Inertsil ODS columns are general-purpose reversed phase C18 columns, available in 5-µm and 10-µm particle sizes. It was the first of the ODS columns from GL Sciences, introduced back in 1986. We currently recommend InertSustain C18 or Inertsil ODS-4 columns for all new method developments.
